The soiledulere ferred to in these Letters Patent and making part of the same.

-Be it known that wefPAUh Oousm and Prnnnn OURY, of thecity of Paris, in the. Empire of France,

1 i a have invented certain new and useful Improvements in. Decorative, Murahi Qleo- Ohromo Oil Painting, of which the following is a specifioatiomthe same liavingbeenpatented by us in France, under date of April 19, 1869.

.Nobody, has succeeded, up to the present time, to

app ly, by'mao hinery, the oil-painting on walls or 1 panels fordccorating the interior or exterior of buildings. This is the result we'propose to obtain by the process which is-theobject of the present application for Letters Patent; I

I The name we give to our invention clearly shows its essential character, .which consists in applying the process usedin chronic-lithography to print designs in oil-colors, on an intermediate paper, from which the same canthen be transferred by the.process of decalcoinauie." p

Another specialty of our invention consists in thevarious means that we have devised for the preparation of the transferpaper, of the colors to be transfer-red, and finally, ofthepaste requiredto cause the adherence of the decoration to the wall.

lowing, step by step,- the various operations of which it consists.

We will take the process at itsinception. Supposing,

for instance, thatsolne design or plan, invarious col-' 'ors, has heenselected, and that it is desired to reproduce it in oil-colorsone or more times upon a wall;

in a word, that we wish to reproduce it in a mural painting.

iWe at first take some very thin,'unsized paper, such as-is generally used, and steep it, on one side only, in

, sizing. H I I The sizing employed is strained through very 'fine linen, and then heatedby steam up to a temperature of from sixty to seventy degrees,

Its peculiar virtue is to be exempt from all kind of fermentation, and by means of the oily substance which it transfersto the paper, forms a varnish, which is water-proof, and 'which protects the paper from the action of all foreign. substances.

This special sizing of the paper may be done by hand; or by means ofa machine provided with a fine brush, under which the paper must be passed without stopping. The paper is then allowed to dry at an ordinary temperature. p

p A design, composed of several figures or symbols, has been previously made in one or more colors. From this design several platesor stones are engraved, a number equal to .the various colors. The various operations are then earned on, only theordcr em- :ploye d'in chrome-lithography is reversed, that is'to say,.that the bright colors are put on first, and the We take No. 1 Almacica gum, No. 2 Sierra-Leone gum, and "to this we add crude oil as a siccative. In order to render these substances agglutinal and oily, they must be heated up to500 or 600.

l The color can only be mixed with linseed-oil when used for decoration, and never with essences; but for the ground-coaiing, the color must only be mixed with essences, and not with oil. After the color has been mixed, care niust be taken to add No. 1 andNo. 2; no matter what the preparation may be.

I After the printing has been made on all the plates perfectly prepared, the paper is impregnated with the ;design, in all its colops, and is in readiness to be used for the transfer of the design to the walls or panels, and, in general, to all fiat surfaces which it may be desired to decorate.

The wall or panel must be cleaned, and, if need be, moistened, and then ,the paper applied, after, how- ;ever, having spread upon it a paste on'the side of the l ground-coating. We will now give a description of our'process, fol- This paste is prepared from barley flour, and it is uvell to add a solution of alum, with a sprinkling of black pepper and camphoi". These precautionary measures will have the effect of protecting the painting from insects and dampness.

g In affixing to the wall the sheets of paper bearing the design, and the paste, its transparency will serve as a guide to attain precision in joining.

The appliance being terminated, the'decalcomanic may be proceeded with at once, but it is better to ,allow it to dry during about ten hours. The sheet of paper is dampened with aspouge, and becomes detached, and falls almost by itself, leaving .all the pa'intingon the wall, to which it is thus transferred with all the dist-inctness of outline, and all the brilliancy of color. Moreover, it adheres and is fixed to the wall with greater security than a painting by the brush.

i If a varnishedpainting is desired, the varnish is afterward applied to the wall, or a coat of varnish is applied to the paper, before the same is printed in colors.

The engraved plates may be of metal, with the do sign in basso or alto-rel'ieuo, according to the nature of preparing'paper, and applying thereto designs in 4. The paper, with the designs printed thereon,

oil-colors, and transferring the same to walls or other and ready for transfer, as herein described, as a new surfaees,as set forth. article of manufacture for mural decoration.

2. The use of paper, when treated or prepared, as PAUL GOUSIN. herein described, for the reception andtransfer of des, PIERRE OURY. signs in oil-colors, as set forth.

3. The use of Alruacica, SierraLeone, or similar Witnesses: gums, when treated, substantially as herein described, J. U. ZUST, and combined with oil-colors, for the purpose set forth. DAVID T. S. FULLER.
